I have a 2008 G35x sedan and I'm looking to replace the timing chain, gears, tensioners and guides. My water pump went out and I figure while I'm that far in It's a good time to do everything. I've looked up kits , but most just list G35. Are the VQ35DE and the VQ35 HR parts interchangeable? I'm also looking to change the gallery gaskets (if needed) as well. Any help would be much appreciated. Thanks, John
